Loris Guignard is a product-minded engineering leader with 14+ years building high-scale distributed systems and a track record from founder/CTO roles to VP and Principal Engineer positions. Based in Paris, he blends hands-on full‑stack development with team leadership, shipping reliable APIs, real-time systems and polished front-end components. He has contributed to notable open-source projects—improving job scheduling in Agenda, hardening FeathersJS REST behavior, and enhancing popular React UI components—demonstrating both backend rigor and UI sensitivity. His background spans startups and scale-ups (Gowento, Splio, Qobuz) where he drove engineering strategy, product thinking and operational reliability. Unusually for a senior leader, he remains an active code contributor across TypeScript, Node.js and React ecosystems, writing tests and distribution builds himself. He holds an ENSIIE Master’s in Computer Science and brings a pragmatic, product-first approach to complex technical challenges.
